Existem muitas causas de diarréia em pacientes que são transplantados, incluindo o efeito dos agentes quimioterápicos e as infecções. Neste estudo, foram avaliados 47 pacientes que receberam transplante no HU-UFJF entre maio de 2011 e maio de 2013. Todos os pacientes que apresentaram diarréia tiveram suas amostras de fezes enviadas para análise e pesquisa de agentes etiológicos através de exames específicos para fungos, coccídios, Strongyloides, parasitas intestinais, Clostridium difficile, e bactérias patogênicas. Trinta e nove pacientes (83%) tiveram diarréia, sendo que, destes, 35% tiveram diarréia induzida por quimioterapia, sete (17,5%) apresentaram coccídios, três (7,5%) tiveram Cândida sp, um (2,5%) Clostridium difficile e um paciente (2,5%) apresentou Giardia lamblia. Outros 30% apresentaram diarréia por outras causas. Houve uma tendência a mais diarréia em pacientes com mais de 50 anos (p=0.09), naqueles que receberam condicionamento com lomustina, etoposide, citarabina e melfalam (p=0.083) e houve um maior número de dias de neutropenia nos pacientes com diarréia (p=0.06). Porém nenhum fator de risco foi encontrado. Os dados apontam para a importância da correta identificação dos agentes etiológicos e da alta probabilidade de variações destes agentes em populações distintas. / Diarrhea is a major cause of morbidity for the patients undergoing high-dose chemotherapy and autologous hematopoietic stem cell transplantation (ASCT). There are multiple causes of diarrhea in patients undergoing transplantation incluing antineoplastic chemotherapy and infections. In this study, 47 patients underwent ASCT at the HU-UFJF between May 2011 and May 2013. All patients who presented with diarrhea consented to stool sample analysis for identification of the etiological agents through specific exams in search of fungi, coccidia, intestinal parasites, Strongyloides, C. difficile, and other pathogenic bacteria. Thirty-nine patients (83%) had diarrhea, among whom 35% had diarrhea induced by chemoterapy, seven (17.5%) presented with coccidia, three (7.5%) with Candida sp., one (2.5%) with C. difficile, and one (2.5%) with Giardia lamblia. Other 30% had diarrhea for other causes. There was a tendency toward a higher incidence of diarrhea in oldest 50 years (p=0.09) and those who received lomustine, etoposide, cytarabine, and melphalan conditioning (p=0.083) and a higher number of days of neutropenia in patients with diarrhea (p=0.06); however, no risk factors were identified. The results shows the importance of correctly identifying the etiological agent and highlights the possible varieties of agents in specific populations.
